Description

CROSS-REFERENCE TO RELATED APPLICATIONS

N/A.

FIELD OF THE INVENTION

The present invention relates generally to the field of flagpole accessories, and more particularly to methods and systems for illuminating a flag of a flagpole.

BACKGROUND OF THE INVENTION

American flags should be displayed from sunrise to sunset every day according to the U.S. Flag Code. However, if a flag owner wants to display a flag during nighttime, this is permissible as long as the flag is illuminated.

Lighting systems for flags are available but they are typically ground mounted, which tends to cause inefficient illumination of the flag. Additionally, such ground mounted lighting systems are not eligible for DARK SKY™ certification. There are some lighting systems available for downlight mounting on a top end of the flagpole, but the mounting structure of such systems tend to obscure and interfere with efficient illumination of the flag.

As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for illuminating a flag of a flagpole.

SUMMARY OF THE INVENTION

The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of illuminating a flag of a flagpole.

In an aspect, a flagpole lighting device can include:

- a) A mounting stem, which can be connected to a flagpole truck that is mounted on a top of a flagpole; and
- b) A dome assembly with an illumination dome, such that the dome assembly is connected to a top end of the mounting stem; wherein the dome assembly can further include:
  - at least one light source, which can be mounted on an inner surface of the illumination dome;
- such that light from the lighting source is reflected in the illumination dome, such that the flagpole lighting device provides lighting for a flag mounted on the flagpole.

In a related aspect, the flagpole lighting device can further include:

- a mounting structure, which connects to on an inner surface of the illumination dome, such that a top end of the mounting stem connects to a central portion of the mounting structure.

In a further related aspect, the mounting structure can further include:

- a plurality of mounting arms, that extend radially from the central portion of the mounting structure, such that an outer end of each of the mounting arms is connected to the inner surface of the illumination dome.

In a yet further related aspect, the dome assembly can further include:

- a plurality of mounting receptacles, which are mounted on the inner surface of the illumination dome, such that an outer end of each of the mounting arms is connected to a corresponding mounting receptacle.

There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.

- wherein an outer end of each of the mounting arms 336 is connected to the receptacle body 326, such that the receptacle fastener 232 protrudes through the mounting aperture 337 and into the receptacle aperture 327. The receptacle fastener 232 can screw into the receptacle aperture 327 or it can be a receptacle plug 232, which is permanently glued into the receptacle aperture 327, for example using a PVC adhesive, such as “plumbing glue”, or a solvent cement.

In a further related embodiment, as shown in FIGS. 3B and 3C, the central portion of the mounting structure 230 can further include a central aperture 331, which includes a female threading 333;

wherein the mounting stem 140 is hollow, such that the mounting stem 140 comprises a stem aperture 346, which protrudes through the mounting stem 140;

- wherein a top end of the mounting stem 140 comprises a male threading 349; wherein a top end of the mounting stem 140 is connected to the central portion of the mounting structure 230, such that the top end of the mounting stem 140 is screwed into the central aperture 331 of the mounting structure 230.

In a yet further related embodiment, as shown in FIG. 2A, the flagpole lighting device 110 can further include a power wire 244, which can protrude through the mounting stem 140 and the central aperture 331 of the mounting structure 230, such that the power wire 244 is connected to the at least one light source 228.

In a further related embodiment, as shown in FIG. 3B, each of the light emitting diode strips 228 can be radially mounted, extending from a central area 342 of the inner surface 224 towards a rim 344 of the illumination dome.

In a further related embodiment, as shown in FIG. 3B, each of the light emitting diode strips can be mounted along a radial middle line 340 between a first mounting arm 338 and a second mounting arm 339, i.e. in a middle 340 between the first mounting arms 338 and the second mounting arm 339 such that there is an equal shortest distance to either the first mounting arms 338 and the second mounting arm 339 along the radial middle line 340.

Thus, in another related embodiment, as shown in FIGS. 2A, 2B, 3A, 3B, and 3C, a flagpole lighting device 110 can include:

- a) A dome assembly 120, which comprises:
  - ii. an illumination dome 121; and
  - iii. at least one light source 228, which can be mounted inside (i.e. within) the illumination dome 121, i.e. in the interior of the illumination dome 121 between an opening 222 and an inner surface 224 of the illumination dome 121;
- wherein the dome assembly 120 can be configured to be connected to a top end of a flagpole 160;
- such that the dome assembly 120 is configured to be positioned with an opening 222 of the illumination dome 121 pointing downward, when the dome assembly 120 is connected to a top end of a flagpole 160;
- such that light 118 from the at least one light source 228 is directed downward by the illumination dome 121, such that the flagpole lighting device provides lighting for a flag mounted on the flagpole 160, and such that the illumination dome 121 prevents emissions of upward directed light 118.

In related embodiments, the flagpole lighting device 110 replaces light fixtures that illuminate from the ground up. The flagpole lighting device 110 can be configured to use 24V DC, whereas many other flag lighting products use line voltage and are therefore less safe during installation and use. The flagpole lighting device 110 limits upward illumination and is therefore DARK SKY™ compliant and eligible for DARK SKY™ certification. Regardless of the position of the flag, the flagpole lighting device 110 remains stationary and provides lighting in a 360-degree span of illumination. The mounting stem 140 can include a weep hole 246 for drainage, and a wire exit aperture for installation of power wiring 244 to the at least one light source 228.

In related embodiments, the flagpole lighting device 110 can universally mount to different flagpole truck assemblies 150, as provided by various manufacturers.

Here has thus been described a multitude of embodiments of the flagpole lighting device 110, the flagpole lighting system 100, and methods related thereto, which can be employed in numerous modes of usage.

The many features and advantages of the invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention, which fall within the true spirit and scope of the invention.

Many such alternative configurations are readily apparent and should be considered fully included in this specification and the claims appended hereto. Accordingly, since numerous modifications and variations will readily occur to those skilled in the art, the invention is not limited to the exact construction and operation illustrated and described, and thus, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
